"native VLAN" on Cisco usually means "non-tagged frames".

So in your scenario: VLAN 100 needs to be tagged, VLAN 201 must not be
tagged.

(I seem to remember that *some* version of IOS for switches can also 
set the native VLAN to tagged - so if in doubt, check with the person
administrating the Cisco switch how they want to receive the frames)
